James K. Hammitt

Professor of Economics and Decision Sciences

Center for Risk Analysis



Professor Hammitt's research concerns the development and application of quantitative methods—including benefit-cost, decision, and risk analysis—to health and environmental policy. Topics include management of long-term environmental issues with important scientific uncertainties, such as global climate change and stratospheric-ozone depletion, evaluation of ancillary benefits and countervailing risks associated with risk-control measures, and characterization of social preferences over health and environmental risks using revealed-preference, stated-preference, and health-utility methods. He has served on six National Academies of Sciences panels, more than a dozen advisory committees to the U.S. Environmental Protection Agency and other government agencies, is a fellow of the Society for Risk Analysis, and in 2015 received the SRA’s Distinguished Achievement Award for “for extraordinary achievement in science or public policy relating to risk analysis.”
